In their weekly bulletin published on 9 March the Standards and Testing Agency announced some slight changes to the deadlines for data collection and the publication of Key Stage 2 test results (now scheduled for 11th July 2023).
In the same bulletin there are links to electronic calendars confirming all the final dates and deadlines. The calendars can be downloaded from the primary assessments future dates page on GOV.UK and the dates imported into an existing calendar in a matter of seconds.
